r2-transfer-service-playbook

To coordinate R2 transfer pipeline changes, this playbook analyzes updates across Python services, Cloudflare Workers, and PHP loggers to enforce domain validations, token injections, and regression checks for safe deployments.

Validating an R2 transfer workflow requires setting R2_BASE_URL, R2_FETCH_TOKEN, and ALLOWED_R2_DOMAINS as environment prerequisites to enforce domain allowlists and ensure resilient updates before deploys.

You can test an R2 worker safely by running the test_r2_worker.sh script to validate the transfer workflow, utilizing dry-run deployments to verify headers, logging, and domain validations without production impact.

Yes, the R2 transfer playbook enforces logging configurations that explicitly exclude PII, ensuring auditable updates across Python services and PHP components while maintaining compliance during pipeline modifications.

The best way to enforce domain allowlists for Cloudflare Workers is by configuring ALLOWED_R2_DOMAINS, which the playbook validates to deliver resilient and auditable updates across the transfer pipeline.

Yes, you can use this playbook to simultaneously update r2_transfer_service.py and email_processing/orchestrator.py, coordinating changes to delivery links and r2_url configurations with mandatory regression checks.
